Pieced Balls

2005. Hand-pieced. The book Patchwork Puzzle Balls by Jinny Beyer inspired these pieced balls.
They're based on various polyhedra -- made from regular polygons.
Patterns (called 'nets') for polyhedra can be found at Mathworld (
mathworld.wolfram.com). Stuffing the stitched polyhedra makes them into balls.

Icosidodecahedron. 5-inch diameter. Made of 20 triangles and 12 pentagons.

Rhombicuboctahedron. 4-inch diameter. Made of 18 squares and 8 triangles.

Rhombic triacontahedron. 5-inch diameter. 30 diamonds, Tumbling Blocks pattern. I used 60 flannel triangles to make this
ball for the friend who supplied the fabric. I won't make that mistake again.
Flannel is not tightly-woven enough to use for these balls.
